In the present study, we illustrated a facile fabrication of large scale ultra‐thin silver sulfide (Ag 2 S) nanowires (NWs) and its promising application in hydrogen evolution reaction (HER). Ultra‐thin and highly uniform Ag 2 S nanostructures were fabricated from single‐source precursor [(PPh 3 ) 2 AgS 2 P(O i Pr) 2 ], and characterized by utilizing various structural and imaging techniques. Large‐scale monodispersed ultra‐thin single‐crystalline Ag 2 S nanowires were generated via n‐decylboronic acid induced thermal decomposition of the single precursor in the presence of octadecyl amine and oleyl amine mixture under anaerobic conditions. We explored the catalytic activities of Ag 2 S nanowires for HER which showed an overpotential of−88 mV at 10 mA/cm 2 and the corresponding Tafel slope was found to be 52 mV dec −1 .
